Planes crash on runway

Probable cause: The other pilot’s failure to see and avoid the other airplane landing in the opposite direction on the runway. Contributing to the accident was the other pilot’s failure to use the correct runway call sign in his radio communications. 

Lack of recent night flight experience contributes to crash

Probable cause: The pilot’s geographic disorientation while maneuvering in the airport traffic pattern in dark night conditions, which resulted in the airplane descending below a normal approach path and a collision with trees. Contributing to the accident was the pilot's lack of recent night flight experience.
